摘要

The hydroboration of 2-vinyl and 2-allylpyrrole with various hydroborating agents [Et2BH2BEt2,(9-BBN) 2,(CH2) 4BH2B (CH2) 4, thex (H) BH2B (H) thex, Az-BH2—THF (Az= pyrrole, 2, 5-dimethylpyrrole, indole), Et2O-BH2Cl, Me3Si (H) NB2H5] leads in most cases finally to B-substituted bicyclic N-pyrrolylboranes 8–11, 15–20. In the case of the reaction with tetraalkyldiboranes (6), stable intramolecular 2-H-pyrrole-borane adducts 6, 7, 12–14 ...
